This transformation moves every point in a figure a given distance in a given direction (hint: slides)
What is a translation?
One figure is _____ to another if it can be moved with translations, rotations, and reflections to fit exactly over the other.
What is congruent?
All dilations are similar, but they are not ___.
What is congruent?
What is rise over run?
This is the term for when the line starts at the origin point
What is a proportional relationship?
This transformation moves every point on a figure around a center by a given angle in a specific direction (hint: turns)
What is a rotation?
When part of an original shape matches up with part of a copy, we call them this term. These could be points, segments, angles, or distances.
What is corresponding?
This terms is the starting point from which we measure distances in a dilation.
What is the center of dilation?
This is the formula to find slope between two points.
What is y2-y1/x2-x1?
When a line represents a non-proportional relationship, then the line must have this.
What is a y-intercept?
This transformation moves every point on a figure to a point directly on the opposite side of the line (hint: mirror)
What is a reflection?
If two shapes are congruent, they are also this term.
What is similar?
To create a scaled copy, we multiply all the lengths in the original figure by the same number. This number is called this term.
What is a scale factor?
What is y=mx+b?
Find the slope of a line who has the the coordinate points (1,2) and (3,4)
These types of transformations are moves that do not change any measurements of a figure. Translations, rotations, and reflections are examples
What is a rigid transformation?
The sum of two supplementary angles equals this many degrees
What is 180 degrees?
The two triangles shown are similar. Find the value of d/c.

7.5/9 = .833
A cell phone plan costs $200 to start. Then there is a service fee of $50 per month.
a. What is the total cost (start up fee and monthly charge) to use the cell phone plan for 2 months?
b. What is the total cost for x amount of months? Hint: write an equation in the form of y = mx +b that represents this scenario.
a. $300
b. y = 50x + 200
What is the equation for line m?
x = 3
Describe the sequence of transformations that takes Triangle B to the image of Triangle A.
A reflection over the y-axis, then a translation 2 units to the right and 2 units up.
Which images are congruent with Triangle ABC?


These two triangles are similar. Find side length of b.

b = 15
Does the point (10,5) exist on the line whose equation is represented by y = 2x - 15?
Yes.
5 = 2(10) - 15
5 = 20 - 15
5 = 5
Which of the ordered pairs are solutions of the linear equation 2x+3y=12?
a. (5,2)
b. (0,6)
c. (3,2)
C.
